Reverse osmosis treatment for the industrial sector
Reverse osmosis technology is a widely used industrial solution for obtaining high-quality water, both for obtaining water as a high-value raw material, allowing you to obtain safer and higher-quality products, and for minimizing the environmental impact of your industry's activity by treating your wastewater.
How our industrial reverse osmosis water purifier can help you
Among its most notable features and advantages we find:
- Removal of impurities and contaminants: It is capable of removing up to 99% of contaminants, thereby obtaining very high quality water free of impurities.
- Optimization of industrial processes: This technology allows obtaining very high quality water, with a low mineral load, ideal for closed circuit water usage processes, since it requires less system purging as it can be used for more cycles.
- Extends the life of the installation: By eliminating dissolved minerals that can damage both pipes and equipment, due to the sediments that can accumulate from the precipitation of salts, this system allows extending the useful life of the installation, especially in cooling circuits or process points where there is a heat input.
- Sustainability and waste reduction: When faced with highly complex effluents, reverse osmosis treatment allows minimizing the amount of contaminated water, rejecting almost all residual compounds and concentrating them into a small fraction, thus reducing the cost of their management.

Technical specifications for industrial reverse osmosis treatment
This is how the most efficient filtration system works:
Membrane filtration
Reverse osmosis treatment is based on a semipermeable membrane through which the water to be purified passes. To achieve this, a pressure greater than the osmotic pressure is applied to the inlet stream, forcing the water to flow in the opposite direction to its natural flow—hence the term "reverse"—and thus purifying it. In this way, the membrane only allows water to pass through, trapping contaminants such as bacteria and viruses. The result is high-quality, pure water.
Equipment
Among the main elements found in a reverse osmosis system are: the pump, which exerts pressure so that the influent can pass through the membrane leaving the contaminants behind; and the reverse osmosis membrane, a membrane with tiny pores that only allows water to pass through and blocks the rest of the impurities.
Maintenance and pretreatment
Besides these key elements, because it is a very sensitive membrane, it requires specific care, such as a water pretreatment process with filters to retain larger particles and reactions to precipitate compounds that could damage it. It also needs control systems and sensors to adjust key operating parameters and a washing system to ensure its efficiency.

Benefits of installing an industrial reverse osmosis plant in your company
Among the benefits of installing a reverse osmosis wastewater treatment or feedwater plant in your industry are:
Zero waste
Virtually complete elimination of impurities and contaminants: they are capable of removing up to 99% of the impurities present in the water.
Performance optimization in industrial processes
It is an autonomous system where the worker only needs to perform minor supervision. Furthermore, by removing impurities from the water, the lifespan of the system's pipes is extended due to reduced sedimentation.
Significant reduction in operating costs
It consumes little energy per amount of purified water, and does not require many reagents depending on the type of water to be treated.
Long membrane lifespan
If properly treated, the membranes can have a lifespan of between three and six years and are easy to replace, so it is only necessary to stop the installation for a few hours for conditioning.
Strict compliance with quality standards
Reverse osmosis allows for obtaining high-quality water that meets increasingly strict discharge parameters.
Sustainability and lower environmental impact
Since it does not require chemical reagents for its use, it generates less waste. In addition, by obtaining quality water, it can be reused, reducing the company's dependence on water and making the process more environmentally friendly.

Frequently asked questions about industrial reverse osmosis installation
What is the difference between an industrial reverse osmosis water purifier and other filtration systems?
In membrane filtration, such as reverse osmosis, the membranes operate using pressure, so a pump is usually needed to overcome the osmotic pressure. The difference between this technology and other filtration methods lies in the passage of contaminants through the membrane; reverse osmosis technology offers the lowest contaminant removal rate of any filtration method on the market.
The combination of technologies is common. To properly care for a membrane with small pores, such as that used in reverse osmosis, other filtration processes with larger pores, such as microfiltration, ultrafiltration, or nanofiltration, are used beforehand to remove impurities that, due to their size, could damage the reverse osmosis system.
Do industrial reverse osmosis water treatment systems require frequent maintenance?
If the prior water conditioning process is adequate, and no elements that could damage the membranes reach them, the lifespan of these membranes is between three and six years or even more, and they only require some daily control (since their parameters are monitored) and automated washings, to remove the film that is generated with the trapped residues and to maintain their filtration efficiency.
Is reverse osmosis for industrial water efficient at reducing contaminants?
Reverse osmosis is the technology used to remove contaminants and obtain high-quality water. It is widely used in the food, pharmaceutical, and chemical industries where the incoming water must meet strict specifications, as well as when water needs to be regenerated at the end of an industrial process, where regulations also impose stringent quality requirements.
Which industries can benefit from reverse osmosis for industrial water treatment?
Reverse osmosis water treatment is widely used for desalinating seawater and brackish water, softening water, pretreating boiler water (to remove minerals that can damage the circuit by corroding the pipes), ice making, the food industry, power generation (pure water for green hydrogen generation), the chemical industry, the pharmaceutical industry, water regeneration processes, the electronics industry, and even for purifying industrial wastewater, the metallurgical industry, etc.
What are the requirements for installing a reverse osmosis plant in a company?
The key to installing a reverse osmosis plant in a company without damage—that is, ensuring its efficiency and long lifespan—is to properly treat the water beforehand. This involves taking all necessary steps to remove components that could clog or damage the membrane due to their size, as well as chemical compounds that could corrode it. These contaminants must be precipitated and removed from the water stream before it enters the reverse osmosis process. By following these steps, and with proper cleaning and monitoring of the system, the membranes, which are expensive pieces of equipment, can be expected to have a long lifespan. These treatments can also be designed and installed by SITRA.
